I am trying to use g_serial as console(gadget serial). For that I am calling register_console() from gserial_setup() function. But this is getting stuck at acquire_console_sem(). When I printed semaphore count it is infact 1, but internally it is getting stuck at down() function spin lock(). Any idea what it could be ? I have patch which enables gserial as console. I want to get the kernel prints on USB port(don't have uart on our board). Regards, Ramesh.
